New Nanomaterials To Remove Antibiotics From Water

 

 

Antibiotics has been widely used as a veterinary medicine and as medication for humans. However, it also has been an emerging pollutant in water.


for its environmental residues increase the resistance of bacteria. What's worse, resistance genes continuing to expand and evolve in the environment could even create "super bacteria".


Given this, a study team led by Prof. KONG Lingtao from Institute of Intelligent Machines under Hefei Institutes of Physical Science has synthesized the new Zr-MOFs nanomaterials successfully to remove antibiotics from water.


The researchers used a simple hydrothermal method to synthesize the Zr-MOFs (UiO-66-NH2) with excellent stability in water and applied them to the experimental study of removing norfloxacin (NOR) antibiotics in water.


The adsorption capacities of UiO-66-NH2 reached a maximum of 222.5 mg/g for NOR, which were considerably higher than that of most reported adsorbents.


At a concentration of 10 mg/L, the highest partition coefficient of 20.9 mg/g/¥ìM was obtained, and the removal rate of NOR was as high as 91.6%, implying that UiO-66-NH2 offered considerable adsorption performance at a low concentration of NOR.


Finally, several credible adsorption mechanisms were proposed.


This work was supported by the State Key Research Development Program of China, the Natural Science Foundation of China and the Science and Technology Major Projects of Anhui Province.
